Note Author(byg10stpd) :This mod is aimed at providing better power balance between trucks at similar experience levels. This mod provides 11 new engines and 21 more options for customization. Many of the engine upgrades are available earlier in progression to provide better balance between makes, all of the engines should be unlocked by level 20. A lot of the starter trucks should have higher baseline power, but the smaller engines are still available if you wish to use them.

Level 0: 1900-2100nm torque engines for starter trucksLevel 2: up to 2100nm torque Level 4: up to 2200nm torqueLevel 6: up to 2300nm torqueLevel 8: up to 2400nm torqueLevel 10: up to 2500nm torqueLevel 12: up to 2600nm torqueLevel 14: up to 2700nm torqueLevel 16: up to 2800nm torqueLevel 18: up to 3200nm torqueLevel 20: all engines should be unlocked

I also tweaked the engine brake to better match that of engine displacement, bigger engines provide better brake horsepower.
